Knowledge of the evolution of the human genome depends on the availability of informative genetic markers to sustain phylogenetic reconstruction. In recent years, advanced genotyping technologies have enhanced the resolution of genome wide analyses by using hundreds of thousands (300 K to 650 K) of single nucleotide polymorphisms (SNPs) [1 (http://www.biomedcentral.com/1756-0500/8/174#B1)]-[3 (http://www.biomedcentral.com/1756-0500/8/174#B3)]. In recent years, data generated by large scale Next-Generation Sequencing (NGS) projects [4 (http://www.biomedcentral.com/1756-0500/8/174#B4)] have promised a fuller evaluation of genetic variation of the nuclear genome. However, for autosomes, genetic recombination, allelic gene conversion and natural selection complicate the phylogenetic reconstruction. Instead, because it does not recombine and has low reversion and recurrence rates, the male specific portion of the Y chromosome (MSY) can furnish key information about human evolutionary history.

every year now, more than 10.000 new SNPs are mapped
visibility will become very clear as more and more detailed info of subclades start seeping in
